T o all whom t may concern.'

Be it known that I, DANIEL B. JACOBS, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Doubletree-Clip, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved doubletree clip arranged to allow convenient attachment of the clip to doubletrees of various thicknesses and width, to permit of adjusting the clip in case of shrinkage of the wood of the doubletree, to securely hold the clip in position, and to allow use of the clip at the middle of the doubletree for connection with the draw pin and hammer strap as well as on the ends of the doubletree for connection with the swingletree.

Tn order to accomplish the desired result use is made ot' top and bottom plates extending from the top and bottom of the doubletree and projecting beyond the sides thereof, fastening means connecting the ends of the said plates with each other at one side of the doubletree and connecting and retaining means between the other ends of the plates at the other side of the double tree. Use is also made of a bolt connecting the ends of the plates with each other, and a spool held on the said bolt for engagement by the connecting link or ring of a swingletree to support the latter from the clip at the end of the doubletree.

A practical embodiment of the invention is represented in the accompanying drawings torminga part of this specication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a plan view of the clip as applied to a doubletree mounted on the pole of a vehicle; Fig. 2 is an enlarged plan View of one of the clips as applied to the end of the doubletree; Fig. 3 is a cross section of the same on the line 3-3 of Fig. 4; Fig. A is a sectional side elevation of the same on the line 4 4 of Fig. 2; Fig. 5 is a sectional side elevation of a modified form of the attaching means of the clip; Fig. 6 is a similar view of another modified form of the attaching means; Fig. 7 is a like view of another modiied form of the attaching means; Fig. 8 is a perspective view of a modified form of the clip; Fig. 9 is a sectional side elevation of the same; Fig. l0 is a plan view of the blank for forming the top plate of the clip shown in Figs. 8 and 9; Fig. ll is a similar view ot' the blank for forming the bottom plate of the clip shown in Figs. S and 9; Fig. l2 is a plan view of another modied form of the clip; and Fig. 13 is a side elevation of the same.

As shown in Fig. l, the doubletree A is held on the top of the vehicle pole B and provided with the usual hammer strap C and draw pin D adapted to engage a clip E held on the middle ot the doubletree A, similar clips E being arranged at the ends of the doubletree for connection with the links or rings F for supporting the swingletrees from the said clips E', as hereinafter more fully explained.

Fach of the clips E and F/ is formed of a top plate G and a bottom plate H, the plates extending across the top and bottom of the doubletree A, the said plates G and H being provided with extensions G', G2 and H', H2 extending beyond the opposite sides of the doubletree A. rThe extensions G, H are provided with integral flanges G3, H3 eX- tending toward each other and fitting against the corresponding side of the doubletree A, and the said extensions G and H are provided with lugs G4 and Ht extending toward each other and merging with the ianges G3 and H3. Bolts it pass loosely through the extension G and the lugs G4 and screw into the lugs H* thus connecting the plates G and H with each other at one side oli the doubletree A. l/Vashers or aliners J are interposed between the lugs G4, H4 and the flanges G3, H3, and in case the doubletree A shrinks the said washers can be removed to allow of drawing the plates G and H tight again on the top and bottom of the doubletree A by correspondingly screwing up the bolts I. rThe eXtensions G and H are provided intermediate the bolts l with registering apertures H5 for the passage of the draw pin D to hold the doubletree A in place on the pole B and hammer strap C, as plainly indicated in l other at the other side of the doubletree A by a bolt K extending loosely through the extension G2 and screwing into the extension H2, as plainly shown in Figs. il, 5, 6 and 7. On this bolt K is held a spool L and washers N are mounted on the bolt intermediate the upper and lower ends of the spool and the corresponding extensions G2, H2 so that in case the doubletree A shrinks and the plates G and H are adjusted then one or several of the washers N may be removed to compensate for the shrinkage in the thickness of the doubletree A. The spool L is engaged by the link or ring F of the swingletree to be supported from the end clips E. The under surface of the top plate G is provided with an integral rib G6 and a similar rib HG is formed on the top of the bottom plate H, and the said ribs GG, H extend in staggered relation across the doubletree A and engage grooves therein so as to securely hold the top and bottom plates Gf and H from lateral displacement on the doubletree A. The middle clip E may be provided with a spool L and washers N on the bolt K, but preferably a hook O is employed having a hub O fitting onto the bolt K intermediate the extensions G2, H2, as shown in Fig. 7. By this arrangement the doubletree A may be conveniently hooked onto the ring on the clevis of a plow or the like, whenever it is desired to use the doubletree for suoli a purpose, instead of on a vehicle, as shown in Fig. 1. ln a like manner a clevis P may be directly engaged with the bolt K instead of the spool L or the hook O, as shown in Fig. 6. As indicated in Fig. 5, the bottom plate H has its extension H2 diverging into a return bent hook H7 to confine the ring F in the hook H7 and thus prevent the swingletree frombecoming accidentally detached from the corresponding clip E of the doubletree A.

In the modified form shown in Figs. 8, 9, 10 and 11, the clip is formed of a top plate Q and a bottom plate R, both preferably formed of flat blanks, as indicated in Figs. 10 and 11. lThe plate Q is provided with angular arms Q', Q2 and similar arms R', R2 are formed on the bottom plate R, the said arms extending toward each other and fitting opposite sides of the doubletree on which the clip is to be used. rIhe arm Q is provided with an outwardly-extending horizontal flange Q3 and the arm R terminates in an outwardly-extending doubledup flange R3 also forming an eye Rt. The fianges Q3 and R2 are connected with each other by a bolt S which extends through the flange R3 to permit of drawing the plates Q and R tightly in position on the top and bottom of the doubletree. rlhe arm Q2 terminates in a fiange Q4 and the arm R2 terminates in a doubled-up flange R5, and the flanges Q4 and R5 are connected with each other by a bolt T which extends loosely through the fiange Q4 and screws in the doubled-up flange R5. A spool U is held on the bolt T for engagement by the link or ring F to support the swingletree from the corresponding clip on the doubletree. T he plates Q and R are provided with struck-up ribs Q5, RG adapted to engage corresponding recesses in the tcp and bottom of the doublei tree to hold the clip against lateral movement.

In the modified form shown in Figs. 12 and 13, the top and bottom plates V and W are provided at-one end with a filling piece K secured in place by bolts Y extending through the top plate V and screwing in the bottom plate W. The filling piece K is adapted to abut against one side of the doubletree, and its outer face is provided with an eye K for engagement by a draw pin to hold the doubletree in position on the pole. rlfhe top plate V and the bottom plate W are provided at the ends opposite the filling piece K with angular arms V, W terminating in flanges V2, `W2 connected with each other by a bolt T, on which is mounted to rotate loosely a spool U similar to the spool U above mentioned. rllhe bolt T extends loosely through the fiange V2 and screws in the flange W2. The top plate V and the bottom plate W are provided with ribs V3 and `W2 adapted to engage the top and bottom of the doubletree to hold the clip against lateral movement on the doubletree.

lt is understood that the clip shown in Figs. 8 and 9 as well as the clip shown in Figs. 12 and 13 can be used either on the middle of the doubletree A or at either end thereof, the same as the clips E and E above described and shown in Fig. 1.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
